Diastolic and Systolic Cardiac Dysfunction in Pectus Excavatum: Relationship to Exercise and Malformation Severity.

Purpose: To explore stress echocardiographic findings among patients with pectus excavatum (PEX) and their relationship with malformation severity.

Materials And Methods: A prospective registry involving consecutive patients with a diagnosis of isolated PEX referred to undergo chest CT and stress echocardiography to evaluate surgical candidacy and/or to define treatment strategies was developed. Malformation indexes were evaluated using chest CT.

Anatomic or functional testing in stable patients with suspected CAD: contemporary role of cardiac CT in the ISCHEMIA trial era.

One of the foundations of the management of patients with suspected coronary artery disease (CAD) is to avoid unnecessary invasive coronary angiography (ICA) referrals. However, the diagnostic yield of ICA following abnormal conventional stress testing is low. The ability of ischemia testing to predict subsequent myocardial infarction and death is currently being challenged, and more than half of cardiac events among stable patients with suspected CAD occur in those with normal functional tests.

Relationship between left atrial dimensions and global and regional fat depots.

Background And Objectives: The relationship between body fat depots and the left atrial (LA) dimensions has not been fully explored. Our objective is to determine if there is a relationship not only with total body fat depots, but specifically with regional fatty depots.

Materials And Methods: It was an observational, retrospective study that included consecutive patients referred to our institution with an order to perform computed tomography angiography triggered by electrocardiogram for different clinical indications.

Preoperative multimodality imaging of pectus excavatum: State of the art review and call for standardization.

Purpose: Image acquisition protocols and reports in patients with pectus excavatum (PEX) differ significantly from routine examinations, and no imaging modality can enable a comprehensive assessment of PEX severity and cardiac impact within a single examination. We therefore attempt to establish recommendations about preoperative imaging in patients with PEX.

Method: Chest computed tomography (CT), stress echocardiography (Echo), and cardiac magnetic resonance (CMR) allow the evaluation of specific information regarding structural and functional characteristics of vital importance to assess surgical candidacy and define surgical strategies.

Invasive coronary angiography findings across the CAD-RADS classification spectrum.

The recently introduced coronary artery disease reporting and data system (CAD-RADS) evaluated by computed tomography and based on stenosis severity, might not adequately reflect the complexity of CAD. We explored the relationship between CAD-RADS and the spatial distribution, burden, and complexity of lesions by invasive coronary angiography (ICA). Stable patients who underwent coronary computed tomography angiography (CCTA) and ICA comprised the study population.

Sternal torsion in pectus excavatum is related to cardiac compression and chest malformation indexes.

Background/purpose: The role of sternal torsion (ST) in patients with pectus excavatum (PEX) is unknown. We evaluated the relationship between ST and both chest malformation and cardiac compression (CC) indexes.

Methods: We included consecutive patients with PEX who underwent chest computed tomography and cardiac magnetic resonance (CMR) to define surgical candidacy.

Impact of pectus excavatum on cardiac morphology and function according to the site of maximum compression: effect of physical exertion and respiratory cycle.

Aims: Previous studies have demonstrated diverse cardiac manifestations in patients with pectus excavatum (PEX), although mostly addressing morphological or physiological impact as separate findings. Using multimodality imaging, we evaluated the impact of PEX on cardiac morphology and function according to the site of maximum compression, and the effect of exertion and breathing.

Methods And Results: All patients underwent chest computed tomography, cardiac magnetic resonance (CMR), and stress echocardiography (echo) in order to establish surgical candidacy.

Relationship between left atrial dimensions and global and regional fat depots.

Background And Objectives: The relationship between body fat depots and the left atrial (LA) dimensions has not been fully explored. Our objective is to determine if there is a relationship not only with total body fat depots, but specifically with regional fatty depots.

Materials And Methods: It was an observational, retrospective study that included consecutive patients referred to our institution with an order to perform computed tomography angiography triggered by electrocardiogram for different clinical indications.

Atherosclerotic plaque burden evaluated from neck to groin: effect of gender and cardiovascular risk factors.

We explored the impact of gender and cardiovascular risk factors (RF) in the distribution and burden of coronary and extra-coronary atherosclerotic plaques among patients undergoing ECG-gated thoracoabdominal computed tomography angiography (CTA) from the supra-aortic trunks to the femoral arteries. We included a consecutive cohort of patients who underwent ECG-gated thoracoabdominal aortic CTA from the supra-aortic trunks to the pubic symphysis. We evaluated the number of coronary segments with plaques [segment-involvement score (SIS)]; and the extra-coronary atherosclerotic plaque burden, comprising the aorta and supra-aortic trunks, iliofemoral arteries, and visceral arteries (extra-coronary SS).

Role of Iterative Reconstruction Algorithm for the Assessment of Myocardial Infarction with Dual Energy Computed Tomography.

Rationale And Objectives: Low monochromatic energy levels (40 keV) derived from delayed enhancement dual energy cardiac computed tomography (DE-DECT) allow the evaluation of myocardial infarcts (MI) among stable patients, although at the expense of high image noise. We explored whether the application of adaptive statistical iterative reconstruction (ASIR) to 40-keV DE-DECT (unavailable with previous software versions) might improve image quality and detection of MI in stable patients.

Materials And Methods: We prospectively enrolled patients with a history of previous MI, and performed delayed-enhancement cardiac magnetic resonance (DE-CMR) and DE-DECT within the same week.

Prognostic Value of Vascular Calcifications and Regional Fat Depots Derived From Conventional Chest Computed Tomography.

Purpose: The prognostic value of vascular calcifications as well as of regional fat depots has been reported separately, in population-based studies, and using gated-computed tomography (CT) examinations. We, therefore, explored the interplay and prognostic value of vascular calcifications and adipose tissue depots assessed during conventional nongated chest CT.

Materials And Methods: We enrolled a consecutive series of 1250 patients aged between 35 and 74 years who underwent clinically indicated chest CT scans.

Coronary computed tomographic imaging in women: An expert consensus statement from the Society of Cardiovascular Computed Tomography.

This expert consensus statement from the Society of Cardiovascular Computed Tomography (SCCT) provides an evidence synthesis on the use of computed tomography (CT) imaging for diagnosis and risk stratification of coronary artery disease in women. From large patient and population cohorts of asymptomatic women, detection of any coronary artery calcium that identifies females with a 10-year atherosclerotic cardiovascular disease risk of >7.5% may more effectively triage women who may benefit from pharmacologic therapy.

Evaluation of pectus excavatum indexes during standard cardiac magnetic resonance: Potential for single preoperative tool.

Purpose: Preoperative assessment of patients with pectus excavatum (PE) demands evaluation of malformation indexes, generally with chest computed tomography (CT). In addition, assessment of the cardiac impact of sternal depression has become a rule in high referral centers, thus requiring two independent imaging modalities and use ionizing radiation in a very young population. The objective of this study was to explore the agreement between chest CT and standard cardiac MR (CMR) for the evaluation of chest wall malformation indexes.

Regional differences of fat depot attenuation using non-contrast, contrast-enhanced, and delayed-enhanced cardiac CT.

Background: Regional fat density assessed by computed tomography (CT) has been suggested as a marker of perivascular adipose tissue inflammation. Dual energy CT (DECT) allows improved tissue characterization compared to conventional CT.

Purpose: To explore whether DECT might aid regional fat density discrimination.

Relationship between cardiac MR compression classification and CT chest wall indexes in patients with pectus excavatum.

Background/purpose: In pectus excavatum (PE) patients owing to the location of the heart in the chest cavity, the most affected site of compression by the depressed chest wall is the right heart, and surgical repair has shown to provide a significant relief in the RH cavities compression. Our aim was to explore the relationship between the site of right cardiac compression, chest wall indexes (CT-CWI) and the sternal torsion angle (STA) based on cardiac magnetic resonance (CMR) and computed tomography (CT) among PE patients.

Methods: We included PE patients with no previous surgical correction referred to CMR and chest CT imaging as presurgical evaluations.

Diagnostic Performance of a Novel Coronary CT Angiography Algorithm: Prospective Multicenter Validation of an Intracycle CT Motion Correction Algorithm for Diagnostic Accuracy.

Objective: Motion artifact can reduce the diagnostic accuracy of coronary CT angiography (CCTA) for coronary artery disease (CAD). The purpose of this study was to compare the diagnostic performance of an algorithm dedicated to correcting coronary motion artifact with the performance of standard reconstruction methods in a prospective international multicenter study.

Subjects And Methods: Patients referred for clinically indicated invasive coronary angiography (ICA) for suspected CAD prospectively underwent an investigational CCTA examination free from heart rate-lowering medications before they underwent ICA.

Pericardial and visceral, but not total body fat, are related to global coronary and extra-coronary atherosclerotic plaque burden.

Background: To explore the relationship between coronary and extra-coronary atherosclerotic plaque burden with total and regional fat depots among patients undergoing ECG-gated aortic computed tomography angiography (CTA).

Methods: The subjects of this study comprised a cohort of consecutive patients who underwent ECG-gated thoracoabdominal CTA. We assessed the number of coronary segments with plaques (segment-involvement score, SIS); and the extra-coronary atherosclerotic plaque burden, comprising the aorta and supra-aortic trunks, iliofemoral arteries, and visceral arteries (extra-coronary SS).

Comparative diagnostic accuracy of dual-energy CT myocardial perfusion imaging by monochromatic energy versus material decomposition methods.

Purpose: To compare the diagnostic value of monochromatic and material decomposition (MD) dual- energy computed tomography (DECT) imaging for the evaluation of ischemia.

Methods: Patients with suspected coronary artery disease underwent rest-stress DECT and SPECT perfusion imaging. DECT images were reconstructed between 40 and 140keV and through MD of iodine/muscle.

Detection of Myocardial Infarction Using Delayed Enhancement Dual-Energy CT in Stable Patients.

Objective: The objective of our study was to explore whether delayed enhancement dual-energy CT (DECT) allows the detection of myocardial infarcts in stable patients.

Subjects And Methods: Patients with known or suspected coronary artery disease clinically referred for myocardial perfusion imaging using SPECT were prospectively included. All patients (n = 34) also underwent stress, rest, and delayed enhancement DECT on a DECT scanner.

Impact on mortality of coronary and non-coronary cardiovascular findings in non-gated thoracic CT by malignancy status.

Purpose: The prognostic value of coronary artery calcification (CAC) assessed on non-gated thoracic CT scans has only been explored in population-based studies. We explored the impact of the presence and extension of CAC, as well as of non-coronary atherosclerosis cardiovascular findings (NCACVF) in survival of patients with and without malignancies undergoing clinically indicated non-gated thoracic computed tomography (CT) scans.
